Abstract

The present invention relates to the technical field of cross-mirror tracking, and discloses a method, device, computer equipment and storage medium for assisting in the realization of high-precision cross-mirror tracking by using video spatial relations, that is, to establish each camera first and be able to transform pixel coordinates into world coordinates After determining the tracking target, the current world coordinates of the tracking target can be obtained through the data model. Finally, according to the current world coordinates, several surrounding cameras are compared and screened using various intelligent analysis algorithms to achieve In the real-time video images of these peripheral cameras, the purpose of high-precision identification and tracking of targets is achieved, thereby enhancing environmental adaptability and The overall accuracy of cross-mirror tracking is improved, which is conducive to effectively improving the efficiency of public security arrests.

Description

technical field [0001] The invention belongs to the technical field of cross-mirror tracking, and in particular relates to a method, a device, a computer device and a storage medium for assisting in realizing high-precision cross-mirror tracking by applying a video space relationship. Background technique [0002] Cross-camera tracking technology refers to a method of effectively identifying and retrieving pedestrians or objects under cross-camera or cross-scene, that is, re-identifying or recognizing pedestrians or objects under different camera lenses, so as to achieve different camera lenses. The effect of tracking the target below. [0003] In recent years, in order to actively respond to the complex situation of social and public security, local security departments have increased the investment and construction of video surveillance systems, and strengthened the coverage of video perception networks. It provides a powerful technical means for public security video pat...
